{"id":"CVE-2026-32933","state":"PUBLISHED","title":"AutoMapper Vulnerable to Denial of Service (DoS) via Uncontrolled Recursion","description":"AutoMapper is a convention-based object-object mapper in .NET. Versions prior to 15.1.1 and 16.1.1 are vulnerable to a Denial of Service (DoS) attack. When mapping deeply nested object graphs, the library uses recursive method calls without enforcing a default maximum depth limit. This allows an attacker to provide a specially crafted object graph that exhausts the thread's stack memory, triggering a `StackOverflowException` and causing the entire application process to terminate. Versions 15.1.1 and 16.1.1 fix the issue.","publishedAt":"2026-03-20T02:38:41.105Z","updatedAt":"2026-03-20T20:02:58.558Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["LuckyPennySoftware AutoMapper"],"affected":[{"vendor":"LuckyPennySoftware","product":"AutoMapper","versions":[{"version":">= 16.0.0, < 16.1.1","status":"affected"},{"version":"< 15.1.1","status":"affected"}]}],"references":["https://github.com/LuckyPennySoftware/AutoMapper/security/advisories/GHSA-rvv3-g6hj-g44x","https://github.com/LuckyPennySoftware/AutoMapper/commit/0afaf1e91648fca1a57512e94dd00a76ee016816","https://github.com/LuckyPennySoftware/AutoMapper/releases/tag/v15.1.1","https://github.com/LuckyPennySoftware/AutoMapper/releases/tag/v16.1.1"],"weaknesses":["CWE-674"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32933.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32933","state":"PUBLISHED","datePublished":"2026-03-20T02:38:41.105Z","dateUpdated":"2026-03-20T20:02:58.558Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-17T00:05:53.282Z"},"containers":{"cna":{"title":"AutoMapper Vulnerable to Denial of Service (DoS) via Uncontrolled Recursion","descriptions":[{"lang":"en","value":"AutoMapper is a convention-based object-object mapper in .NET.
